Antioxidant activity of cactus pear fruits and bioavailability of betalan components in healthy humans

2008

Consumption of fruit and vegetables is now associated with protection against various pathologies, including cancer and cardiovascular and cerebrovascular diseases, in which oxidative damage is an important etiologic factor. Various compounds from plant food, acting independently of known nutrients and micronutrients, have appeared very important in protecting human health. Most of these components can act as antioxidants or affect redox-dependent cell activities involved both in physiological and pathological events. In this scenery fruits of cactus pear (Opuntia ficus-indica), and the characteristic betalain pigments have recently attracted the attention of researchers. While suggesting m…

Assortment, but not knowledge of assortment, affects cooperation and individual success in human groups

2017

The success or failure of human collective action often depends on the cooperation tendencies of individuals in groups, and on the information that individuals have about each other's cooperativeness. However, it is unclear whether these two factors have an interactive effect on cooperation dynamics. Using a decision-making experiment, we confirm that groups comprising individuals with higher cooperation tendencies cooperate at a higher level than groups comprising individuals with low cooperation tendencies. Moreover, assorting individuals with similar cooperation tendency together affected behaviour so that the most cooperative individuals tended to cooperate more and the least cooperativ…

Parasitoids (Hymenoptera) of leaf-spinning moths (Lepidoptera) feeding on Vaccinium uliginosum L. along an ecological gradient in central European pe…

2011

Parasitoids of leaf-spinning Lepidoptera associated with two isolated central European peat bogs were investigated. Five families of parasitoid Hymenoptera (Braconidae, lchneumonidae, Eulophidae, Pteromalidae and Encyrtidae) were recorded. Three categories were recognised: (1) primary parasitoids, (2) facultative hyperparasitoids and (3) obligatory hyperparasitoids. Ten species of Braconidae, five species and seven marked morphospecies among lchneumonidae, and three species of Chalcidoidea were identified. Despite of some niche-specific (but less host-specific) parasitoids, all these hymenopterans are likely to be generalists and none of them were confirmed to be habitat and/or host special…

El Niño in the Eocene greenhouse recorded by fossil bivalves and wood from Antarctica

2011

[1] Quasi-periodic variation in sea-surface temperature, precipitation, and sea-level pressure in the equatorial Pacific known as the El Nino – Southern Oscillation (ENSO) is an important mode of interannual variability in global climate. A collapse of the tropical Pacific onto a state resembling a so-called ‘permanent El Nino’, with a preferentially warmed eastern equatorial Pacific, flatter thermocline, and reduced interannual variability, in a warmer world is predicted by prevailing ENSO theory. If correct, future warming will be accompanied by a shift toward persistent conditions resembling El Nino years today, with major implications for global hydrological cycles and consequent impact…

A study of major and trace element accumulation in humic acids

2015

It has been widely studied recent as well as historic accumulation of elements in peat profiles depending on intensity of anthropogenic pollution and thereby peat profiles serve as archives for research of environmental change. Peat ability to accumulate major and trace elements depends on the character of element supply, potency of metal ions to bind functionalities in the peat structure, pH reaction, oxygen presence, presence of complexing compounds, inorganic ions and many other factors. The aim of this study is to assign major and trace element distribution in humic acids (HA) for two well characterized ombrotrophic peat profiles of Eipurs and Dzelve Bog and analyse factors affecting el…

Peat florulas in the Madonie Regional Park (Sicily)

2009

The floristic exploration of the eastern slopes of the Madonie Mountains in Sicily, carried out between 1975 and 1980, resulted in the discovery of several hydromorphic environments characterized by a thick peaty horizon. Locally named “margiu” or “triemula”, depending on the lower or higher depth, they host plant communities characterized by some species of Juncus and Carex together with acidophilous bryophytes including some species of Sphagnum. Their ecology as well as their flora and vegetation have been studied (Petronici et al. 1978). In some localities fossil pollens have also been examined (Bertolani Marchetti et al. 1984). Floristic analyses pointed out some phytogeographical patte…

Electrofishing as a new method to search for unknown populations of the endangered freshwater pearl mussel Margaritifera margaritifera

2017

1. The freshwater pearl mussel Margaritifera margaritifera is threatened throughout its Holarctic range, but the occurrence of this species is insufficiently mapped. For the conservation of M. margaritifera, it is important to identify populations more comprehensively. 2. Traditionally mussels have been searched for visually using techniques such as diving and aquascope, both of which are potentially time-consuming and demanding survey methods. 3. In this study, a new search method is presented. As glochidia of M. margaritifera are larval parasites on gills of salmonid fish, electrofishing and non-destructive examination of salmonids with the naked eye may reveal the presence of glochidia a…

From the Normative Heaven to Crude Matter. The Discursive Transformation of Good Government into Governance

2017

International audience; Abstract. The abundant use of the concept of good governance in political and media discourse can lead us to conclude that we are currently encountering a conceptual innovation. In actual fact it is an old concept that has its roots in classical political theory and resists any clear and precise definition. This article aims to reflect on the main changes experienced by the concept of good government and its metamorphosis into governance, by means of an analysis using a narrative of conceptual transformation from a normative logic to a technocratic logic.; Del cielo normativo a la tosca materia. La transformación discursiva del buen gobierno en gobernanza 1 María Áng…

Opettaja työrauhan rakentajana luokkahuoneen vuorovaikutuksessa

2018

Työrauhaongelmat ovat viimeaikoina herättäneet runsaasti peruskoulua koskevaa keskustelua. Vuorovaikutus työrauhan takaamiseksi kouluissa näyttää nousevan keskeiseksi opettajan asiantuntijuudessa. Tämän tutkimuksen tarkoituksena on ymmärtää työrauhan rakentumista opettajan ja oppilaan välisessä vuorovaikutuksessa. Tavoitteena on selvittää, millaisissa tilanteissa työrauha estyy ja millaisilla luokanhallintakeinoilla opettajat puuttuvat oppilaiden työrauhaa häiritsevään käyttäytymiseen. Neljää peruskoululuokkaa havainnoitiin yhden koulupäivän ajan, yhteensä viisitoista oppituntia. Aineistoanalyysinä käytettiin teoriaohjaavaa sisällönanalyysiä. Oppilaiden työrauhaa häiritsevää käyttäytymistä …
